Description

Technical Field

[0001] The utility model relates to the technical field of automobile ball joint structure design, in particular to a self-compensating automobile ball joint structure. Background Art

[0002] At present, the self-compensation of automobile ball joints is to compress the ball pin seat itself and then compensate for the wear clearance of the spherical pair. In this self-compensation method, the wear of the spherical pair itself is the wear of the ball pin seat, so this self-compensation has little effect on compensating the stiffness and torque of the ball joint, and is not effective in improving the durability of the ball joint.

[0005] Furthermore, the angle between the conical surface and the horizontal plane is 1° to 2°.

[0006] Furthermore, the base plate is made of steel, and the ball pin seat is made of POM.

[0007] Furthermore, a riveted closing portion for limiting the position of the bottom plate is provided at the bottom of the ball pin sleeve.

[0008] Furthermore, a stop step is provided on the top of the spherical surface of the ball pin sleeve, and the top of the ball pin seat abuts against the stop step.

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1

[0020] The following is further described in conjunction with specific embodiments. Figure 1-Figure 3 As shown, the utility model is a self-compensating automobile ball joint structure, comprising a ball pin body 1, a ball pin seat 2, a ball pin sleeve 3 and a bottom plate 4. The ball head of the ball pin body 1 is arranged in the ball pin seat 2 to form a spherical friction pair, the ball pin seat 2 is arranged in the hollow cavity of the ball pin sleeve 3, the bottom plate 4 is arranged at the bottom of the hollow inner cavity of the ball pin sleeve 3, and the bottom of the ball pin sleeve 3 is provided with a rivet closing portion 31 for limiting the position of the bottom plate 4.

[0021] In this embodiment, the bottom plate 4 is made of steel, and the ball pin seat 2 is made of POM. The top and bottom surfaces of the bottom plate 4 are both tapered surfaces 41, and the angle between the tapered surface 41 and the horizontal plane is 1° to 2°. The central area of ​​the top surface of the bottom plate 4 abuts against the ball pin seat 2, and a certain elastic deformation can occur. When the spherical pair of the ball joint is worn, the bottom plate 4 can apply an upward thrust to the ball pin seat 2, so as to achieve the self-compensation function of the ball joint in the axial direction. Compared with the bottom plate 4 with a planar structure, the bottom plate 4 with a certain tapered structure can greatly improve the self-compensation performance of the spherical pair of the ball joint without affecting the fit.

[0022] Furthermore, a stop step 32 is provided at the top of the spherical surface of the ball pin sleeve 3, and the top of the ball pin seat 2 abuts against the stop step 32. The setting of the stop step 32 improves the limit swing-out torque and pull-out force of the ball joint structure, thereby improving the performance of the ball joint. At the same time, the setting of the stop step 32 and the setting of the tapered bottom plate 4 together form the action and reaction force on the ball pin seat 2, further improving the self-compensation function of the wear of the spherical surface pair of the ball joint.

[0023] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
